Abstract

The invention discloses a preparation method of a rosin emulsifying agent. The preparation method comprises the following steps: adding rosin, ethyl alcohol and acrylic acid sequentially into a reaction kettle, heating and melting, warming to 150-160 DEG C, stirring and reacting so as to obtain acrylic acid modified abietate, and cooling to room temperature, wherein the weight ratio of rosin, ethyl alcohol and acrylic acid is 1 to (0.2-0.3) to (0.3-0.5); adding deionized water into acrylic acid modified abietate, heating, melting, warming to 150-160 DEG C, stirring while adding octoxinol dropwise, and cooling to room temperature at the stirring speed of 400 turns / min-600 turns / min, thereby obtaining a rosin emulsifying agent, wherein the weight ratio of acrylic acid modified abietate, deionized water and octoxinol is 1 to (0.1-0.15) to (0.03-0.05). The preparation method of the rosin emulsifying agent is simple in technology and is low in production cost, and the prepared rosin emulsifying agent is small in particle size and is stable in storage.

Description

technical field [0001] The invention relates to the technical field of rosin deep processing, in particular to a preparation method of a rosin emulsifier. Background technique [0002] Rosin is one of the natural resins with great economic value and is a valuable renewable resource. The double bond in the acid structure of rosin resin is one of the active centers, so it is usually introduced appropriate groups through the double bond in the resin acid to achieve the purpose of modification. Rosin emulsifier is also a product obtained by modifying rosin as raw material. Because the molecular structure of rosin resin contains a fat-soluble phenanthrene ring skeleton structure, it is difficult to emulsify. Traditional methods require the use of toxic organic solvents, high-pressure homogeneous pumps or higher temperatures to emulsify. Therefore, emulsifiers are not only expensive and cause great environmental pollution, but also cause more side reactions during the emulsifica...
